  • Patent number: 5526087
    Abstract: A photosensitive material processing apparatus includes a drying device for drying with drying air a photosensitive material processed with processing solutions; a waste-solution recovering section, having an absorbing material, for recovering waste solutions of the processing solutions discharged from a plurality of processing tanks due to the absorbing material being impregnated with the waste solutions; and a waste-solution drying device having a duct for introducing warm air from the drying device into the waste-solution recovering section and adapted to dry a recovered waste solution. Since the waste solution is dried by the waste-solution drying device after recovery of the waste solutions of the processing solutions, intervals of maintenance provided for the waste-solution recovering section are extended, and the operating efficiency in waste solution processing is improved.

  • Patent number: 5452524
    Abstract: A photosensitive material drying method for drying a photosensitive material conveyed along a conveying path, including steps of: training a front surface and a rear surface of the photosensitive material alternately around a plurality of heat rollers whose outer circumferences are heated by heat sources; heating the photosensitive material by an amount of heat provided on a basis of a temperature of the outer circumferences of the heat rollers and on the basis of a time of contact between the photosensitive material and the heat rollers; and evaporating moisture from a surface of the photosensitive material not contacting the heat rollers. High-quality drying can be effected in a small space and with little use of electric power. Efficient drying in which dimensions of films are stable can be carried out.
